I got my Quick Jack set up and it's pretty much ready to go, although I'm having two issues.

One of the frames is smooth as butter up and down and operates completely silent. The other frame however is smooth going up, fairly smooth going down (although not as smooth as the other frame) and makes a really loud squealing noise (almost like rubber against a slippery floor) when going down and to a lesser extent when raising up.

The same frame that makes the loud squealing noise also will not stay completely bled. I followed the bleeding process and after 4 bleeds the smooth frame was completely fine and I was unable to get anymore air out of it no matter how many times I raised up and down. The frame that squeals however, I have bled about 10 times in a row and still every single time I bleed it, I'm still getting air out of it.

I suspect the fact that it continuously has air coming out during bleeds and the loud squeal noise have something in common with each other. Can anyone guide me in the right direction at what exactly the problem is?

Here is a YouTube video showing the squealing noise. In the video the frame on the left is the one I'm having problems with. The frame on the right doesn't make a sound. Everything you hear is coming from the frame on the left.

Not familiar with the Quick Jack, but a little familiar with hydraulics and it sounds like you have a bad/leaking seal somewhere.

 

Would you think that would be something within the system itself or one of the fittings I put on?

 

Could be either, I'd do a thorough inspection of the entire system. If air is getting in, fluid must be getting out somewhere. Hopefully someone who has a Quick Jack will chime in and provide more help.

 

On the squealing frame there is no fluid exiting. Not one drop. Except for the tiny amount when I open the bleeder screw. But it's almost nonexistent.

 

Havent had this issue with my Quickjack. Sounds like maybe the Schrader valve maybe loose. Is the side making niose holding the required air pressure? If the valve is loose it's sucking air hence all the bleeding in the world won't stop the air from sucking into the system.

 

Both of the air pressure cylinders seem to lose air pressure quickly. When I filled them up I checked the pressure and got a reading of 45. If I recheck the pressure again it'll go down significantly. Wasn't sure if it was an issue with my reader or not. But if the valve is loose is there a way to fix that or I need to send back the entire frame?

I'm going to contact quick jack today and see what they say.

 

Okay so this morning I disconnected the long hoses and also unscrewed and re-taped the 90 degree fitting on the squeaking frame. I raised and lowered it a couple times and bled it twice and I'm no longer getting air escaping when I bleed. So that problems seems to have been corrected. The squealing has also gone away.

But the same frame is still not as smooth as the other frame. It raises and lowers just fine and at the same speed as the smooth one but as it's raising and lowering it shudders almost like it's sticking against something.

I called Quickjack and when I told them I have not tried raising my car yet I've just done "empty" raises and lowers they told me this is completely normal. They said it takes time for the seals within the system to get broken in and the only way to break them in is to have load on the frames. When I asked how come my other frame which hasn't had a load yet either is completely smooth, quickjack said it happens but is not unusual or anything.

They also said I should lube the frames straight out of the box (I assumed they were lubed from the factory). The way it's shuddering makes me think maybe some lube would fix the issue. So I'm going to lube it up and then raise the car up and down and see if that corrects the problem.

Just wanted to put as much information here just in case anyone else experiences the same problem.

 

There is a valve tool that is made for replacing schrader valve or just tightening it up. i got mine from snap on years ago but I would assume an auto parts place would carry this also.
I also found charging system with required air pressure was funky, I finally stopped rechecking the air pressure. Set it and forget it.

 

For anyone interested here is the video. You can't really see the frame shuddering but you can certainly hear it shuddering. It almost sounds like it's coming from the hydraulic cylinder when it lowers. It's weird though because when raising it doesn't make a sound, although it still shudders.

Yes, I've already established that as well. I kept checking it and the air pressure was all over the place. I filled it up again, checked once, got a 45PSI reading and screwed on the caps. Not going to mess with it anymore.

 

Read my post right above yours, I seem to have gotten the bleeding issue corrected. We posted at the same time.

 

Mine did not raise evenly without a load, path of least resistance for hydraulic oil, once the car was on it it performed flawlessly and a year and half later still working great.
Glad you got it straitened out. You will love using this jack.

 

Yea hopefully that's the issue (I'm sure it is considering you as well as quickjack mentioned it). I'm going to get some white grease to lube it up and raise the car up. I'm excited to use this thing. Expensive? Sure...but so much more useful than a jack and jackstands

 

So much easier than a jack and stands, you'll love it. Hell I use to detail car so my old *** doesn't have to bend over so much, just sit in roller chair and off I go

 

Just throwing this out there, when I bled mine I stood on top of the QuickJacks to give it some weight. I cycled thru standing on it several times before lifting the Corvette. Since then I've used the QuickJacks on my Corvette, and several other vehicles, with no problems whatsoever.
